PENClL-SHARP'ENER.

Specification of Letters Patent.

Patented Dec. 5, 1 5.

To all whom it vnctg concern:

Be it known that I, JAMES T. HIGGINS, a citizen of the United States,residing at New Brunswick, in the county of MiddleseX and.

State of New Jersey, have invented new and useful Improvements inPencil-Sharpeners, of which the following is a specification.

My invention relates to pencil-sharpeners; and its primary object is toprovide a new and useful device of this character wherein the blockcarrying the end of the pencil to be sharpened and the member carryingthe sharpening element or knife arev arranged for simultaneousadjustment to accommodate for pencils of varying size and to providenovel means for effecting the adjustment of said elements.

A further object of the invention is to provide a pencil-sharpener bymeans of which a pencil may be sharpened without liability of breakingthe lead of the pencil during the operation of sharpening, one which ischeap to manufacture, easily operated, durable and efficient, and onewhich is composed of few parts, so arranged and constructed as not to beliable to become broken or inoperative.

The invention consists in the construction, combination, and arrangementof parts hereinafter fully described, claimed, and illustrated in theaccompanying drawings, which disclose the preferred embodiment of myinvention, and in which I Figure 1 is a perspective view of a pencil:sharpener constructed in accordance with my invention. Fig. 2 is acentral longitudinal sectional view thereof Fig. 3 is a top 7 plan view.Fig. 4 is a top plan view with the knife-carrying member removed. Fig.5is a detail perspective view of the knife-carrying member. Fig. 6 isasimilar view of the bracket carrying a block adapted to support the endof the pencil to be sharpened, and Fig. 7 is a detail perspective viewof the sharpening element or knife.

Referring to the drawings by reference-numerals, 1 designates a casingcomprising a bottom 2 and side walls 3, which project upwardly from thebottom 2 in parallelism.

Pivotally arranged between the sides 3 andv supported thereby is aknife-carrier 4 and a pencil-support 5, which are so arranged as to berelatively adjusted.

6 designates a T-shaped bracket, provided with upwardly-projecting arms7, provided with perforations 8, through which pivotpins 9 pass topivotally mount the bracket in applied position on' the casing. Thebracket is adapted to carry the support 5, which is groovedlongitudinally, as at 9", for the reception of the end of the pencil tobe sharpened. The knife-carrier 4 is provided with a longitudinalopening 10, having the side walls thereof provided with ways 11, andsaid carrier is adapted to be pivotally secured in applied position bythe pivot-bolts 9, projecting into bearings 12, located in the edgesthereof. The knife 13 is adapted to be mounted in the ways 11 formovement back and forth across the support 5, and said knife is providedwith two cutting edges 14, whereby when one cutting edge is worn downthe knife maybe easily reversed to bring into operation the other orunused cutting edge. The knife is provided with a handle 15, whichprojects upwardly above the carrier 4 and by means of which it may bereciprocated in the ways to sharpen a pencil. A block 16 is securedbetween the sides 3 adjacent their forward edges and be tween thebracket 6 and carrier 4. This block is provided with a longitudinalgroove 17 arranged in alinement with the groove 9 whereby a pencil maybe placed in the groove 17 to dispose its end to be sharpened in thegroove 9".

The body of the pencil is adapted to be placed in the groove 17, so asto disposethe end of the pencil to be sharpened in the groove 9. Thusplacing the pencil will present the end of the pencil in a path of themovement of the knife 13, and by moving the knife and turning the pencilthe pencil may be successfully sharpened without breaking the lead.

The groove 9 is conical or tapers rearwardly, as disclosed in Figs. 4and 6 of the drawings, so as to regulate the amount of wood to be cutfrom about the lead of the pencil in a manner that is apparent to thoseskilled in the art.

In order to provide for the adjustment of the carrier 4 and the bracket6, an adjustingscrew is mounted on the block 16, and so connected to theknife-carrier and bracket that the turning of the adjusting-screw willcause the knife and support 5 to either move from or toward each other.The forward end of the block 16 is provided with parallel-arranged ears19, between which the adjustingscrew 18 is mounted for rotary movement.

The carrier 4 has its forward end providedwith a horizontally-disposedflange 20, with which theupper end of the adjusting-screw hasconnection, and the forward end of the bracket 6 is also provided with aflange 21, with which the lower end of the adjustingscrew hasconnection.

It is apparent from the above description, taken. in connection with theaccompanying drawings, that by turning the adjustingscrew one way or theother the carrier and bracket are turned upon their pivots, so as tocause the guide and knife to either approach or recede from each other,whereby the knifesharpener may be adjusted so as to accommodate forpencils of varying diameter.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and mode of operation of theinvention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction maybe made within the scope of the invention without departing from thespirit or sacrificing any of the advantages thereof.

Having thus fully described the invention, what is claimed as new is- 1.In a pencil-sharpener, a swinging sup port for the end of the pencil tobe sharpened, a swinging knife-carrier having a cutter movably mountedthereon, and means for simultaneously swinging both the support and theknife-carrier to move each toward and from the other.

2. In a pencil-sharpener, a swinging support for the end of the pencilto be sharpened, a swinging knife-carrier, said support and carrierhaving a common pivotal connection, and means for swinging said supportand carsoaees rier to simultaneously adjust the same toward and fromeach other.

8. In a pencil-sharpener, a casing, a block carried by said casing andprovided with a groove, a bracket pivotally secured in said casing, asupport carried by said bracket and provided with a groove, apivotedknife-carrier, a knife movable thereon, and an adj ustmg-screw carriedby said block and having connection with the knife-carrier and bracket,whereby the knife-carrier and support are adapted for simultaneousadjustment toward and away from each other.

4. In a pencil-sharpener, the combination of a casing or frame, astationary rest-block thereby to support the body of a pencil, a pivotedsupport for the end of the pencil to be sharpened, a pivotedknife-carrier, and an adjusting device carried by said stationaryrest-block and engaging the swinging support and carrier, whereby thesame may be simultaneously adjusted toward and from each other.

5. In a pencil-sharpener, a casing, a block carried by said casing andprovided with a groove, a T-shaped bracket provided with arms, a supportcarried by said bracket and
